Improved red cell quality after erythroplasmapheresis with MCS-3P

Area of Science:

• Transfusion Medicine
• Blood Component Collection
• Apheresis Technology

Background:

• Standard apheresis systems face challenges in optimizing blood component collection and quality.
• The need for efficient and high-quality red blood cell concentrates (RCC) for transfusion is critical.
• Autologous blood donation programs require adaptable component separation methods.

Purpose of the Study:

• To evaluate the efficacy and quality of red blood cell concentrates (RCC) collected using the MCS-3P cell separator.
• To assess the biochemical and rheological parameters of RCC during a 42-day storage period.
• To determine the suitability of the MCS-3P system for erythroplasmapheresis, particularly for autologous blood programs.

Main Methods:

• Utilized the MCS-3P apheresis system with two distinct programs (RBCP and RBCPS) for red cell apheresis.
• Analyzed biochemical parameters (ATP, 2,3-DPG, pH, free Hb, etc.) and rheological parameters (morphological index, filtration index) of RCC.
• Monitored donation time, volume collected, and donor tolerance in 53 donors.

Main Results:

• Red blood cell concentrates (RCC) collected using MCS-3P demonstrated quality comparable or superior to standard collection methods after 42 days of storage.
• Biochemical markers like ATP and 2,3-DPG were better preserved, indicating reduced collection lesion.
• Rheological parameters, including the filtration/rigidity index, showed significant improvements.
• All collected blood preparations (red cells and plasma) were sterile post-storage.

Conclusions:

• The MCS-3P cell separator effectively produces high-quality red blood cell concentrates and plasma suitable for transfusion.
• Erythroplasmapheresis using the MCS-3P system shows promise for enhancing autologous blood donation programs.
• This technology represents a potential advancement in blood collection methodologies, improving component quality and collection efficiency.
